A 100KB size limit is standard for passport photos, scanned ID cards, signature scans, and photo certificates uploaded to college admission portals and online job applications. Smartphone camera photos can easily take 3MB to 8MB of memory. Compressify shrinks your image files to land under 100KB while preserving sharp facial details and readable document text.

Frequently Asked Questions
Will my image quality suffer when shrinking to 100KB?
At 100KB, passport photos and document scans remain sharp and high quality. Reducing the pixel resolution (e.g. to 800px width) is often sufficient to reach 100KB without dropping quality parameters too low.
Does Compressify work for PNG screenshots?
Yes! Compressify automatically optimizes PNG graphics or converts them to JPEG streams to achieve substantial size drops.
Are my photos saved on a server?
Never. All calculations take place inside your browser's private JavaScript sandbox on your device.
